When deserializing docs that contain `#[inline]` the latest version of rustdoc-types fails with an err: ``` Error: Failed to parse rustdoc JSON: unknown variant `#[inline]`, expected one of `non_exhaustive`, `must_use`, `export_name`, `link_section`, `automatically_derived`, `repr`, `no_mangle`, `target_feature`, `other` at line 1 column 230 ``` This is a minimal repro of the issue: https://github.com/Benjscho/deser-err-repro/blob/main/src/main.rs
